Geomembranes in Tailings Management

What Are Geomembranes?

Geomembranes are synthetic liners made from materials like high-density polyethylene (HDPE), polyvinyl chloride (PVC), or ethylene propylene diene monomer (EPDM). These impermeable sheets act as barriers to contain liquids, gases, and solids, making them ideal for tailings storage facilities (TSFs).

How Geomembranes Are Used in Tailings Management

Geomembranes play a vital role in tailings management by providing containment, protection, and stability. Here’s how they are applied:

1. Lining Tailings Ponds

Geomembranes are used to line the base and walls of tailings ponds, preventing the seepage of toxic liquids and chemicals into the surrounding soil and groundwater. This ensures that harmful substances, such as heavy metals and acids, are safely contained.

2. Heap Leach Pad Liners

In heap leaching operations, geomembranes line the pads where ore is stacked. They prevent the leakage of leaching solutions, such as cyanide or sulfuric acid, protecting the environment and improving recovery efficiency.

3. Capping and Closure

At the end of a mine’s life, geomembranes are used to cap tailings storage facilities. This prevents rainwater infiltration, reduces the risk of acid mine drainage, and promotes vegetation growth for long-term site rehabilitation.

4. Secondary Containment

Geomembranes provide an additional layer of protection in case of primary liner failure, ensuring that any leaks are contained and managed effectively.

Key Benefits of Using Geomembranes in Tailings Management

• Environmental Protection: Prevents contamination of soil, water, and ecosystems by containing toxic tailings.

• Regulatory Compliance: Helps mining companies meet stringent environmental regulations and avoid costly penalties.

• Cost Savings: Reduces the need for expensive remediation and maintenance, offering long-term financial benefits.

• Durability: Resistant to UV radiation, chemicals, and mechanical stress, ensuring long-term performance in harsh mining environments.

• Sustainability: Supports sustainable mining practices by enabling safe waste disposal and site rehabilitation.

Case Study: Geomembranes in Action

A mining operation in Chile successfully implemented 1.5mm HDPE geomembranes to line its tailings storage facility. Over a 5-year period, the geomembranes reduced seepage by 95%, significantly lowering the risk of groundwater contamination. Additionally, the facility’s capping system, which included geomembranes, enabled successful site rehabilitation, with vegetation cover increasing by 40% within two years.
